I am trying to make below layout using bootstrap grid. There is a container <div class="row"> and half width two divs in that (<div1> and <div2>). The <div1>'s height would be changeable as content size. And again, the <div2> should have two child divs(<div2-1>, <div2-2>) that half height of <div1> each. How can I make this layout with Bootstrap grid?
